LOS MAITENES, Chile (Reuters) - Chilean teenagers on a field trip have found what experts say could be a treasure trove of fossils from whales which died millions of years ago.

Teenagers from a school in Concon, a town on the Pacific coast, found the fossils last month in the hills near the village of Los Maitenes, nearly four miles from the sea and 100 miles from the capital Santiago.

They found fossilized jawbones, backbones and ribs of four whales which scientists say likely died 5 million years ago.
